I have to wait for an admin to confirm my registration at the Truespace forums which is taking a disgustingly long time, I thought maybe someone here might now. I figure later versions of Truespace allow you to set a true field of view, but version 3 only uses a relative zoom ratio that ranges somewhere between 0.1 and 4.0. I have searched the net for this and have been unable to find a value to enter in here that = a true 90 degree FoV.
